Mercedes driver Nico Rosberg capitalized on a slow start by teammate Lewis Hamilton to win the Japanese Grand Prix on Sunday and widen his lead in the Formula One drivers' championship.
Rosberg, who started from pole position, controlled the race throughout and finished 4.9 seconds ahead of Red Bull driver Max Verstappen, who held off Hamilton in close racing over the final few laps.
"The start went really well," Rosberg said. "Everything went well, and then it was just controlling the pits and the gaps to Max in the race. It was a perfect weekend to win on this legendary track."
With four races remaining Rosberg holds a 33-point lead over Hamilton.
"It's better that way than the other way round but it's still Lewis that's my teammate, so I always need to reckon with him," Rosberg said.
"He's going to be going for it in the last four races. There's still a long way to go."
The result clinched the constructors' championship for Mercedes for the third year running.
Hamilton, who started second, made another of the poor starts which has been among Mercedes few weak points this season, and dropped back to eighth on the opening lap.
The defending world champion worked his way through the field well. Desperately needing as many points as possible in the championship race, Hamilton attempted a bold passing move on Verstappen on the penultimate lap.
Exiting the Spoon curve just 0.5 seconds back, the Briton tried a move into the chicane but Verstappen blocked his path, and Hamilton was forced up an escape road. Hamilton complained over his team radio that the 19-year-old Dutchman had made his move too late under braking.
It was Rosberg's ninth victory of the season and 23rd in F1, moving the German driver into a tie for 12th place on the career list with Nelson Piquet.
Every driver finished the race, only the seventh time in 952 world championship races that has happened.
